When you divide two decimals, what is it called when you move the
decimal point?

Hi Tyler,
Do you mean when you do something like this?
______ ________
31.45 ) 216.5 ==> 3145 ) 21650.0
There's not really an official name for it, although it might fall
under the category of 'equivalent fractions', since what you're really
doing is this:
216.5 100 21650
------- * ----- = -------
31.45 100 3145
Does that make sense?
